198. "But how can a rule show me what I have to do in this situation? Whatever I do is through some interpretation in agreement with the rule."--No, we should not say this.* But this: every interpretationhangs, together with what is interpreted, in the air; the former cannot serve as support for the latter. The interpretation by itself does not fix the meaning (reference).

"Then is whatever I do in agreement with the rule?"--Let me ask this: what does the expression of the rule--let us say a signpost--have to do with my actions? What is the combination there?--Now something like this: I have been trained to make a particular reaction to this sign, and now I react like this.

But with this you have only given a causal connection, only defined how it occurs that we follow (conform to)this signpost; you have not given that which this following-the-sign really consists in. No (on the contrary), I have indicated that a person follows the signpost only insofar as the signpost has a regular use, a custom.

* - Literally: "No, this should it not mean" or, in English syntax: "No, it should not mean this."
